Sustrans Involvement Under the Active Travel Bill the council have a duty Sustrans commented that this Scheme has been to look at key walking and cycling routes and long overdue and the existing route from Llanfoist to investigate additional routes. Abergavenny is potentially too far away from the “natural” route for pedestrians which avoids what is The Scheme comprises the construction of a shared perceived as an unsafe bridge in the form of cycle path bridge and pedestrian access between Abergavenny/ Llanfoist Bridge. Llanfoist and Abergavenny over the River Usk which will then converge with the existing path on Small However, Sustrans were concerned about the direct road improvements will also be made to Merthyr route from Llanfoist to Abergavenny and therefore Road. recommend the proposed route to be as close to “how the crow flies” route as possible. By potentially Objectives of the Scheme crossing through the new housing estate and promoting the use of the proposed bridge, whilst The objectives of the scheme aim to: promoting a safe and coherent link to other routes and providing great views of the area. Town Centre Most direct route “as the crow flies” (1056m) Proposed Route Option 1 Route likely if route is not direct (1459m) Possible new route using bridge (1864m) Funnel point for walking and cycling due to the A465 Sustrans map showing direct routes from Llanfoist to Abergavenny town 2 Proposed Options for the Location of the Bridge The current proposals include three options Option 2 – indicated in Blue for the position of a shared bridge over the River Usk. Each footbridge will require the Bridge location Option 2 is located construction of footpaths on the southern approximately 800m east of Llanfoist Bridge side of the River Usk to allow access. and will require the construction of a number of footpath options (shown in purple Option 1 – indicated in Green on the figure below) on the southern side of the River Usk in order to link the paths to Bridge location Option 1 is located the existing pedestrian accesses. The approximately 300m east of Llanfoist Bridge Bridge will be located to the south of Castle and will require the construction of a Park Meadows. footpath on the southern side of the River Usk which will be positioned on the banks Option 3 – indicated in Pink of the River Usk and will travel west to link with the A4143 at Llanfoist Bridge. The Bridge location Option 3 is located directly Bridge will be located to the south of Castle adjacent to Llanfoist Bridge, and pedestrian Park Meadows. footpaths will link to the existing pedestrian accesses.

The bridge will have a 55m span and a 5m clear footway width (to be confirmed during detailed design). It is envisaged that the ramps will be constructed with earthworks.
